Title
Gold nanocatalysts supported on heterostructured PbSO4-MCF mesoporous materials for CO oxidation
Abstract

•Heterostructured PbSO4-MCF materials were prepared by in situ growth method.•Gold nanoparticles can be highly dispersed on PbSO4-MCF supports.•Au/PbSO4-MCF showed high catalytic activity and stability for CO oxidation.

Metal oxides are commonly used as the supports of gold nanoparticles for catalytic CO oxidation, whereas metal salts are rarely considered suitable supports. In the present work, we developed a new kind of gold nanocatalyst supported on heterostructured PbSO4-MCF mesoporous materials that was prepared by an in situ growth method using dodecylbenzenesulfonate (SDBS) as a sulfonate precursor. It was found that an Au/PbSO4-MCF (SDBS) catalyst preheated at 300 °C showed high CO conversion below 100 °C. In addition, the stability of selected catalysts was studied as a function of time on stream. Because of the alteration of surface properties, these Au nanocatalysts were highly sinter-resistant.
